Single action audio interface utilising binary state time domain multiple selection protocol

ABSTRACT

An interface protocol for the functional manipulation of complex devices such as consumer electronic devices without the necessity of the visual feedback via textual or graphic data, wherein the sensor functions change with time rather than placement, so that a user action biases a binary state switch, which is correlated to a timed audible audio data stream, the correlation indicating the desired action selected by the user.

FIELD OF THE INVENTION

This invention relates to a user interface. The user interface guidesthe user through option menus and the selection process.

BACKGROUND

The present invention addresses problems presented by conventional userinterfaces, for example in consumer electronic products. It relates to aprocess and the configuration of apparatus that can accurately andautomatically interpret the user's desired selection without therequirement that the user be able to read. One aspect of the interfaceof the present invention resides in its ease of use, especially forchildren, for illiterate people and people less technically able. Thedevice can be embedded inside almost any product, for example, withoutintending to be limiting, telecommunication devices such as cell phonesembedded in a product, without affecting the external aesthetics of theproduct.

Applicant is aware of prior art within the field of user interfaces forconsumer electronic products, for example interfaces employing voicerecognition, graphic touch panels, and intelligent keypads. Such priorart user interfaces for consumer electronic products consist of a broadrange of technology mixes. The current trend is to use a more organicstyle of interface such as voice recognition or graphical interfacesrather than arrays of mechanical buttons. Some devices attempt to guessa user's most probable decisions, making navigating complex decisiontrees more tolerable. The present invention is derived out of necessityfor an easy-to-use interface that, for example, may be embedded inelectronic equipment so for example to operate without a keypad ordisplay.

One object of this invention is to provide an alternative method ofoperating equipment for example such as cellular or wireless telephonesor other devices such as equipment which may be operated using binaryinput devices including but not limited to push buttons, switches,digital signals, microphones, motion sensors, light detectors, rotaryencoders, voice recognition processors, or processes, wherein audioprompts guide the user through options, and the user responds with atimely action to accept or reject the specific option presented during acorresponding time window.

SUMMARY

In the present invention, the user of a device is presented with anaction, an option or a series of options via audio messages. The userindicates acceptance or rejection of an option with a timely action, forexample such as pressing a button disguised within a product such as aplush doll. The timely action must occur during the time window in whichthe audio message implicitly or explicitly indicates the intention toaccept or reject an option. Otherwise, the interface indicates thedefault selection to the device. For example, a default selection may beto cycle a number of times through a menu, for example three times, andfailing getting a response backup one level in a decision tree and againcycle through the menu at that level a number of times, and failinggetting a response backup yet a further level, and so on until theinterface or device is left in a standby mode. The interface is thuswell adapted for use by a child, or for example by a visually impairedperson, or even merely for use by people who are driving automobiles andshould not be taking their eyes from the road ahead, because theinterface does not require an action by the user as no action is treatedas a selection choice thus differentiating from prior art for examplewhich presents a three position tree to a handicapped person thusrequiring an action from the person.

The invention is thus, in one aspect, a process of navigating menus orselecting actions or options. The process may utilize a sensor systemconfigured to behave as a binary state switch along with an audiopresentation and feedback system. These two elements are synchronized topermit correlation analysis of signals, which yields information orsignals that indicate the user's selected option or desired action.

The novelty lies, at least in part, in the ability of a device, such asa binary push button, to select one of multiple options by indicatingthe option as desired or undesired as they are presented through timevia speech. Acceptance or rejection is indicated by the presence of oneor the other of the two possible binary states during the correspondingtime window.

The selection time window can be within the time domain of spoken wordsor sounds of the prompt, which may include quiet time and may alsoinclude, or consist only of other audible queues or music.

This interface protocol permits functional manipulation of complexdevices, such as personal telecommunication devices, consumer andcommercial electronic devices and appliances, motion sensor, lightdetector, rotary encoder, voice recognition processor, without thenecessity of the visual feedback via textual or graphic data. Since thesensor functions change with time rather than placement, both visual andtactile demands placed upon the user are dramatically reduced, offeringan advantage over the complex array of graphic symbols and the symbolicplacement of buttons found on multifunction keypads. In the presentinvention an action is converted to an electrical impulse, which iscorrelated to a precisely timed audible audio data stream. Thecorrelated data indicates the desired action or option selected by theuser. This allows a device such as those listed above to be embedded ina product without altering the external aesthetics of the product. Insome cases, the ability to be hidden within the product will be anessential component of the invention's application.

In a further aspect, the present invention is a communication protocolthat defines the parameters of actions, data transfer, acknowledgmentand response for the purpose of a user interface, for example in aconsumer electronic device. The user/operator listens to a stream ofaudio messages that indicate available options. The user selects anaction, an option or an optional path through a menu tree by eitherdoing nothing, or by biasing, for example such as toggling or otherwisereversing the state of a binary state device, so as to select thealternative choice, action or path available at that moment. When theuser makes no selection, it indicates acceptance of a default choice,direction or action such as backing up a level in a decision or menutree.

In one embodiment, the audio stream may present an ongoing list duringwhich the user intervenes to select the desired option. The defaultaction in this embodiment may then be to merely present the next item inthe list.

The present invention may be described as a time domain multipleselection protocol in which for example, and without intending to belimiting, a binary state indicates a selection by inversion of thebinary state during the defined time window for the desired selectionutilizing mechanical, electromechanical and electronic circuitry. Thepresent invention requires the presence of three key elements, an inputmechanism, an audible output system and a method for keeping track ofthe state of the input device as the messages are being presented. Theuser interface is a timing based multiple selection protocol consistingof mechanical, electromechanical and electronic circuitry for a novelmethod of making and selection from a menu or list of items.

Thus, in summary, the present invention consists of a time domain,multiple selection protocol in which a selection of an option is madeduring the defined time window for the desired action or option. Theaction or option is presented in an audible audio information streamthat is precisely timed or synchronized with the monitoring of sensorsto allow electronic signals to indicate and be processed in such amanner as to yield information regarding the user's choice.

The audio stream presents a series of actions or options from which theuser may select an option via any input device, such as a push buttonswitch. The device may also operate with for example a limited binarystate voice recognition interface, motion sensors, light sensors, etc. Apreset default option is assumed unless indicated by the user causing aninput during the time domain of presentation of information pertainingto the desired option. Presented information is any audio informationthat could be used to indicate the nature of an option and its selectiontime frame.

The configuration of electronic components, circuitry, mechanical orelectromechanical sensors and/or computer software/firmware forproviding information to the user and the host system regarding theuser-desired action or option uses such physical resources and timestamping to determine the user's activity and report information via anelectronic or mechanical signal that a processor can process as aspecific action or intent.

A device incorporating the present invention may operate while embeddedin another product, for example a consumer electronics product, withoutaltering the external aesthetics of the product, and without visuallydisclosing the embedded functionality.

Put another way, the present invention may be summarized as an audioprompted interface device using a time domain multiple selectionprotocol wherein the device includes:

-   -   (a) a device housing,    -   (b) a processor and cooperating memory and a power supply        mounted in the housing,    -   (c) an audio broadcaster mounted in the housing and cooperating        with the processor for audibly broadcasting outside of the        housing a sequenced series of audible prompts supplied by the        processor to the audio broadcaster.    -   (d) an input device or sensor mounted in the housing for        receiving input from a user, in one embodiment the input for        binary biasing of an input switch between opposite binary states        in response to a single prompt of the series of audible prompts,    -   (e) a timer cooperating with the processor, the processor        correlating the response to the single prompt with a        corresponding single time domain within a sequential series of        time domains timed by the tinier, and    -   (f) the processor correlating the single time domain with the        single prompt and executing a single action corresponding to the        single prompt according to an instruction set in the memory,        wherein, if for example the single action is a telecommunication        action, the processor executing the single action in further        cooperation with a telecommunication transceiver mounted in the        housing.

The device housing may be a flexible surface and the input receivermounted beneath the flexible surface. The device housing may have anaudio transmitting surface and the broadcaster may be mounted beneaththe audio transmitting surface.

In one aspect of the present invention, the product or device may be aplush toy, which may have at least one appendage. Such an appendage maybe pivotally mounted to a body of the plush toy. The appendage maycooperate with a processor so that a first position of the appendagerelative to the body switches the processor into a stand-by mode, and asecond position of the appendage relative to the body switches theprocessor into an active mode so as to trigger the series of prompts.Advantageously the appendage is an opposed pair of elongate appendagessuch as arms, legs or the like. The pair of appendages may pivotrelative to the body between a resiliently clamped, closed positionwherein the appendages are adjacent, and a spread position wherein thepair of appendages are spaced apart. The first position may be theclosed position and the second position may be the spread position.

In one embodiment, the first and second positions lie substantially in afirst plane. In a third position the pair of appendages are elevated outof the first plane. In the second position the audio broadcaster audiblytransmits at a first audible volume and in the third position the audiobroadcaster audibly transmits at a second audible volume, wherein thefirst audible volume may be greater than the second audible volume. Inthe third position the ends of the arms, which may be shaped as hands,cup a mouth of the plush toy. In this embodiment the audio broadcastermay be mounted behind the mouth of the plush toy. When the ends of thearms are hands in the first position the hands are together in front ofthe plush toy, and in the second position the hands are widely spreadapart.

In a further aspect of the present invention the input switch may be apush-button switch, and the series of audible prompts may be prompts ina multi-level menu tree. The input switch may also be a microphone inconjunction with software to detect any audible response versus noaudible response, the audible response biasing, for example a binaryswitch to its opposite binary state. The series of audible prompts maycomprise a sequentially audibly broadcast list of names from a list ofnames in the memory, wherein the single prompt is a single name from thelist and the single action corresponding to the single name is to dial atelephone number, from a corresponding list of telephone numbers,corresponding to the single name. Advantageously the list of names maybe statistically ordered based on frequency and time of calling by theuser so as to present first numbers most likely to be called. In onepreferred embodiment, the input button switch may be biased a pluralityof times in rapid succession and the action corresponding to the singleaction is different depending on the number of times the input switch isbiased in rapid succession. In another preferred embodiment the speed ofaudible presentation of the prompts may be increased by compressing theaudio data in the prompts, and in such a case the prompts may be sped-upin an adaptive feedback loop so as to increase the presentation speeduntil user mistakes meet a threshold cut-off level.

The method of the present invention may comprise the steps of:

-   -   (a) audibly broadcasting outside of the housing from the        broadcaster a sequenced series of audible prompts supplied by        the processor to the audio broadcaster.    -   (b) receiving input to the input receiver from a user, the input        for example toggling a binary state input receiver in response        to a single prompt of the series of audible prompts,    -   (c) timing, by the timer, a sequential series of time domains,    -   (d) correlating, by the processor, the response to the single        prompt with a corresponding single time domain within the        sequential series of time domains,    -   (e) correlating, by the processor, the single time domain with        the single prompt, and    -   (f) executing a single action corresponding to the single prompt        according to an instruction set in the memory.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

What follows is an example of one embodiment according to the presentinvention which is not intended to be limiting. Thus, with reference tothe timing diagram of FIG. 1, the upper line describes an audio signal,that is, a plot of signal intensity over time. As a message is spoken orotherwise audibly broadcast to a user by a telecommunication deviceemploying the interface of the present invention, the audible signallevel increases as diagrammatically illustrated in the “audible signal”line and time transpires. The middle and lower lines indicates two ofthe three possible selections, so that in the case where the userdesires to “phone mom”, the user's timely input (for example bysqueezing a flexible toy so as to toggle a push-button switch) wouldcause a waveform having a pulse within the “phone mom” selection timewindow. Thus, waveform “a” would result in a selection to phone mom. Thepulse 10 indicating a state change could have occurred any time betweentime lines 12 and 14. The pulse 16 in waveform “b” is well outside thephone mom selection window and would make a different selection, in thiscase to “phone home”. This is a simple example of the user interface ofthe present invention.

Users of this interface are not required to look at thetelecommunication device during operation, eliminating the need fordisplays and the interpretation of visual symbols on buttons or graphicson the displays, and also eliminating components such as the keypadspopular in the wireless telephone industry today. Also, the user'sfinger, or other selector, can maintain close proximity while making aselection, which makes the device easier, and in some conditions safer,to use. The input from the user may be a physical toggling of a binaryswitch, or it may be non-contact biasing of a binary state switch by,for example, the use of motion or light detectors, or by audible soundsensors, voice recognition etc.

The interface of the present invention is a departure from currentinterface design in its operational style, its elegance and simplicity.However, it does have its drawbacks, it tends to be slow compared tonormal operation of a conventional keypad and is best suited to tasksthat do not require the user to remember past actions. For example,entering long strings of numbers can be taxing for the user.

A physical embodiment of the present invention may have three elements,namely:

-   -   (a) means, such as a processor (including associated memory), a        microphone and a power supply, of generating and broadcasting a        meaningful and audible audio stream which includes a sequential        menu-tree series of prompts to direct the user's        decision-making:    -   (b) a sensor that senses and transmits or applies a signal to        the processor indicating a user input timed to denote the user's        desired option; and,    -   (c) a timing and correlating processor (which may be the same        processor as in (a) above) that correlates in time audio        presentation of the audio stream and user input signals.

Further processing features enhance operation of the interface of thepresent invention, namely:

-   -   (a) statistical ordering; that is, the processing of numbers        such that the numbers that are most pertinent to the user are        determined by statistical analysis based upon both call time and        frequency;    -   (b) audio compression; that is, the process of compressing        sounds so as to increase the speed of presentation of audible        prompts (for example a sequential counting of numbers) in the        time domain while maintaining essential message intelligence for        the purpose of presenting more information in a given instant.        This is desirable for use in a voice prompt based user interface        for example in a personal communications device and may be        accomplished by, for example, removing 40 percent of the        digitized audio data without causing a sound frequency shift;    -   (c) adaptive feedback; that is, monitoring activities that are        subliminal to the user but detectable to the system to control        the nature of the user interface with the intention of making        the user interface more effective for the user. The activities        of most interest in are those that affect the speed of        presenting or processing of information that is fast enough to        keep interest and slow enough to be usable in a reliable manner.        By using audio compression, as the user leaves, the speed of        presentation of the prompts is increased until the processor        detects an increase in user mistakes above a preset threshold;        and,    -   (d) pre-ring messaging so that an identifying name of a caller        is audibly announced to the user (for example: “it's morn”).

What follows is a detailed description of implementation of oneembodiment of the interface of the present invention in the operation ofa telecommunication device embedded in a plush toy. The plush toy isreferred to herein as a “companion telecommunicator” such as it would beperceived by a child if the companion telecommunicator was a favoriteplush doll. The programmed menu structure and logic flow that a userfollows during operation of the companion telecommunicator are set outbelow. Appendix A hereto provides further detail, short of the actualcode, of the sequence scripts for each step in the menu structure.Detailed actual coding is not provided as one skilled in the art wouldknow how to program and implement the interface of the present inventiongiven the level of detail disclosed.

To the user, such as a child, the companion telecommunicator appears totalk naturally, prompting the user with options. By simply squeezing thecompanion telecommunicator, the user places a call, makes emergencycontact, records reminders and saves phone numbers. Call listsmaintained by the companion telecommunicator processor are updated andsorted automatically, chronologically or according to popularity, withmost recent or most frequently called numbers at the beginning. Thecompanion telecommunicator tells the user that someone is calling byannouncing the caller's name, or with a customized greeting, or with astandard telephone ring, a melody or by vibrating.

As seen in FIG. 4, companion telecommunicator 100 attaches to theclothes of a user 102 or for example to a user's backpack (not shown)for transport by the resilient clamping together of the hands 106. Thecompanion telecommunicator may also have loops (not shown) that willattach to key rings or clips for easy transport.

After long periods of inactivity, companion telecommunicator 100 will godormant. Companion telecommunicator 100 is woken up by squeezing itstummy 104 as seen in FIG. 5 gently for three seconds. Companiontelecommunicator 100 greets user 102 then audibly broadcasts that it isin stand-by, speaking or whisper mode. Companion telecommunicator 100may be intentionally made dormant or “put to sleep” by gently squeezingtummy 104 for three seconds. Companion telecommunicator 100 counts down“three”, “two”, “one” then says “good-bye”. Squeezing for three secondswill not however put the companion telecommunicator to sleep during aconversation or while announcing a call.

When companion telecommunicator 100 is in stand-by mode, it is ready toreceive calls. User 102 can ensure that companion telecommunicator 100is awake by giving it a gentle shake. If it giggles, it's awake. Thecompanion telecommunicator's hands 106 are positioned as if clapping toput it in stand-by mode, as seen in FIG. 6. Thus companiontelecommunicator 100 can hold on to user 102 while in stand-by mode asseen in FIG. 4.

Whisper mode is for private conversations. In whisper mode, the audiblevolume is lowered so that user 102 may hold the microphone 108a embeddedin, for example, the mouth 108 of companion telecommunicator 100 near tothe user's ear. Companion telecommunicator 100 is put into whisper modeby lifting arms 110 out of plane A so that it looks like companiontelecommunicator 100 is whispering as seen in FIGS. 5 and 7. Mouth 108of companion telecommunicator 100 is brought to the user's ear so thatthe user can listen for directions.

Speaking Mode allows the companion telecommunicator to speak loudly sothat the audible directions can be heard by a group of people. Companiontelecommunicator 100 is placed into speaking mode by opening the arms110 as seen in FIG. 8. In speaking mode the arms have been rotated inplane A from the clapping position to the spread apart position.

To use companion telecommunicator 100, all user 102 has to do is holdthe companion telecommunicator, listen and squeeze tummy 104, thisdepresses an internal push-button switch 112 mounted in rigid processorhousing 114 seen in FIGS. 9-14. When the companion telecommunicatorspeaks via microphone 108a, the user squeezes tummy 104 so as to depressswitch 112 to tell the companion telecommunicator what the user wants.When the companion telecommunicator is in whisper or speaking mode, ittalks to the user. To make a selection, the user squeezes the companiontelecommunicator while it's talking, or during the moment before thenext selection.

The companion telecommunicator uses a 3.6 volt lithium ion battery (notshown). If the battery is getting low the companion telecommunicatorwill periodically say “low battery”. This alarm will increase infrequency as the battery power gets lower.

Companion telecommunicator 100 uses a mechanical endoskeleton mountedwithin the arms and body of the telecommunicator so as to transmit thearm position information to the processor (not shown) housed withinprocessor housing 114. A shoulder or shelf 116 is mounted onto orotherwise formed on the upper end of housing 114. As better seen in FIG.13, shoulder 116 has an upper planar surface 116a on which are pivotallymounted a pair of arm struts 118. Planar surface 116a is parallel toplane A in which arm struts 118 rotate on stub shafts 120. Rotation ofstub shafts 120 about axes of rotation B transmits the arm positioninformation via a position sensor (not shown) to the processor withinhousing 114. Leaf spring 122 rigidly mounted between stub shafts 120resiliently biases arm struts 118 into either the closed position ofFIGS. 9 and 12 wherein hand paddles 124 mounted on the distal ends ofarm struts 118 are resiliently clamped together or the speaking modeopen position of FIG. 10 wherein arm struts 118 are rotated in directionC into their fully spread apart position.

As better seen in FIGS. 14 a-14 c and FIG. 15, aim struts 118 arethemselves pivotally mounted to stub shafts 120 for rotation relative tostub shafts 120 about axes of rotation D on stub axles 126. Rotating armstruts 118 about axes D allows movement of the arms out of plane A so asto put the arms into the whisper mode position of FIG. 11.

Rotation of arm struts 118 about axes D rotates bevel gears 118 a on armstruts 118 in meshing engagement with crown gear 120 a on stub shafts120. Thus, irrespective of the rotational position of stub shafts 120,elevating and lowering arm struts 118 rotates crown gears 120 a therebysignaling to the processor the vertical position information of armstruts 118. Stub shaft 120 is mounted by means of pin 126 shown explodedradially outwardly in FIG. 15. Thus contrasting FIGS. 14 b and 14 c,although between the two figures the rotational position of stub shaft120 has not changed, the arm strut 118 has been elevated in FIG. 14 cthereby rotating crown gear 120 a relative to stub shaft 120.

An alternative embodiment is illustrated in FIG. 16 in which, aslabeled, all of the various components are built into the processorhousing with the exception of a remote speaker and microphone for whichonly the respective connectors are illustrated.

The housing 114 is enlarged so as to enclose shoulder 116, the gear endsof arm struts 118, the gears, etc. Consistent with all embodiments ofhousing 114, the circuit boards 130 containing the processors, the powersupply, and the audio amplifier are all contained within the egg-shapedhousing, tilted for example as illustrated so as to optimize use of theinterior space of the housing. Arm struts rotate relative to the housingin cut-out channels 128.

The audible menu for the companion telecommunicator works like a menutree. Every choice made by the user leads to more choices until thefunction that the user wants is presented. Some prompts appear in morethan one menu.

When the companion telecommunicator asks “what would you like to do?”the user has several choices. Each choice performs a specific functionor presents more options. The choices are presented in the followingorder: “Present Lists”, “Enter A Number”, “Play Sound Clips”, “RecordSound Clip”, “Provide Status Information”, and “Set Preferences”. Thechoices are audibly repeated by the companion telecommunicatorsequentially several times. If the user does not make a choice, thecompanion telecommunicator returns to stand-by mode.

The “Present Lists” choice lists stored phone numbers to call. Thestored telephone numbers are sorted for presentation depending on thetype of list selected. The choices are “Personal Call List”, “EmergencyCall List”, “Incoming History List” and “Outgoing History List”. ThePersonal Call List is automatically updated, according to frequency ofuse. The Emergency Call List presents the most important numbers first.The incoming History List is updated according to the last number thatcalled the companion telecommunicator. The Outgoing History List sortsthe user's calls, starting with the most recent number.

The “Enter a Number” choice guides the user through telephone numberentry and lets the user add the number to the phone list.

The “Sound Clip” choice lets the user record, play back or delete soundclips. Sound clips may be recorded during conversations, as reminders ortransferred from the network or the user's home computer.

The “Provide Status Information” choice announces the user's phonenumber and the time and date, then tells the user if there are messageswaiting, and reports battery level, signal strength, roaming status,available memory, and the like.

The “Set Preferences” choice customizes the way the companiontelecommunicator responds and presents information.

The user can cancel any choice and return to the previous menu at anytime by squeezing the companion telecommunicator three times.

Any time the user needs assistance on a particular menu item, the usersqueezes the companion telecommunicator's hand 106 when the user is inthat part of the menu. A sensor in the hand triggers the processorprovide context sensitive audible help prompts.

To answer a call in Whisper Mode, the user lifts the companiontelecommunicator's hands 1.06 to mouth 108, then places companiontelecommunicator 100 near the user's ear. To answer a call in SpeakingMode, user 102 opens the companion telecommunicator's arms 110. Thevolume is automatically increased so as to be loud enough for a group ofpeople to hear the conversation.

To terminate a call, user 102 places the companion telecommunicator instand-by mode by closing arms 110.

For the user to place a call using Enter A Number menu:

-   -   1. The user places the companion telecommunicator in Whisper or        Speaking Mode.    -   2. When the companion telecommunicator says “enter number”, the        user squeezes once.    -   3. The companion telecommunicator will count from zero to nine        and say “place call”.    -   4. The user squeezes the companion telecommunicator when the        user hears the right digit.    -   5. The user repeats Step 4 for each digit in the number the user        wishes to call.    -   6. If the user makes a mistake, the user squeezes the companion        telecommunicator twice. When the companion telecommunicator says        “erase last digit entered”, the user squeezes once.    -   7. To review the digits entered, the user squeezes the companion        telecommunicator twice. When the companion telecommunicator says        “review digits entered”, the user squeezes once.    -   8. When the user has entered all the digits in the number the        user wants to call, the user squeezes and holds the companion        telecommunicator—or squeezes the companion telecommunicator when        its says “place call”. The companion telecommunicator will tell        the user the number the user is calling.    -   9.
